Light Bulbs Could be the New Wi-Fi

German physicist Herald Haas attached a special microchip to an LED light bulb and voila! he’s created a potentially marketable VLC (Visible Light Communication) device!  (I’m sure that description seriously simplified the process)

So, what’s VLC?

In order to save energy, LED bulbs flicker many times per second — so fast that one doesn’t notice.  Haas thought that if each flicker sent a coded computer message, then transmitting local wireless Internet would no longer need a WiFi router, just a certain type of light bulb! “LiFi” some are calling it.  It would be pretty awesome if it’s practical and works.

Nonetheless, it’ll be cool to follow how this technology develops.
